Air Pollution 'Triggers Hundreds More Heart Attacks and Strokes,' Study Finds

An anonymous reader quotes a report from the BBC: Higher air pollution in the UK trigger hundreds more heart attacks, strokes and acute asthma attacks each year, research suggests. A team at King's College London looked at data from London, Birmingham, Bristol, Derby, Liverpool, Manchester, Nottingham, Oxford and Southampton. They calculated days with above average pollution levels would see an extra 124 cardiac arrests over the year. On days with high pollution levels, across the nine cities in total, they calculated that there would be a total of 231 additional hospital admissions for stroke, with an extra 193 children and adults taken to hospital for asthma treatment. Dr Heather Walton, of King's College London's Environmental Research Group, said air pollution reduction policies concentrated in the main on effects connected to life expectancy. In London, high-pollution days would see an extra 87 cardiac arrests per year, an extra 144 strokes, and 74 children and 33 adults ending up in hospital with asthma-related issues. In Birmingham the figure would be 12 more out-of-hospital cardiac arrests, 27 additional admissions for stroke and 26 more for asthma. Bristol, Liverpool, Manchester, Nottingham, Oxford and Southampton would see between two and six more out-of-hospital heart attacks and up to 14 extra hospital admissions for both stroke and asthma. Only in Derby would there be no apparent increase. The research suggests cutting air pollution by a fifth would decrease incidents of lung cancer by between 5% and 7% across the nine cities surveyed.Read more of this story at Slashdot.
